An Analytical Study on the Structural Performance of Reinforced Concrete Columns Subjected to Various Loading Histories

다양한 하중 이력을 받는 철근콘크리트 기둥의 구조적 성능에 관한 해석적 연구

This paper compares the moment-curvature relations of reinforced concrete columns subjected to various loading histories. A sectional analysis was proposed to predict the behavior of reinforced concrete columns. The proposed analysis predicted the real moment-curvature relations of reinforced concrete columns with good agreement. Four types of loading programs were adapted to the analysis. The analysed results indicated that the moment-curvature relations of reinforced concrete columns were strongly affected by the loading history.
